Well, for Europeans at least. Rockstar themselves have confirmed that the European release date of Grand Theft Auto: Liberty City Stories has been changed to June 23, two weeks after the American launch. Yes, Americans, the release date for the United States stays the same, June 6.

Also, much to my own personal dismay, confirmed in a review in Issue 82 of the UK's PSW, there is no multiplayer in the PS2 version. The only improvements noticed in the PS2 version were slightly better graphics. However, it did recieve a score of 8 out of 10 from the publication, which is quite a good score. Even with a lack of any new features, cars, weapons, etc., at a score of 8 out of 10 (and at only $19.99!), this port of Rockstar's first criminal simulation endeavor on the PSP is worth the purchase.

slightly off topic= Was the Car Dealership mini-game availabl on the GTA3?
I found that mini-game quite neat on GTA: LCS.

Concerning the delay, if only the graphics improved, meh- No need to get it on PS2 then unles Rockstar makes some cool linkable play like one player plays on PSP the other player plays on PS2 but I guess that won't happen since they confirmed no multiplayer :(
